Iris Scatter Plot
This animated scatter plot explores the Iris dataset by cycling through different feature pairs on the x- and y-axes every three seconds, revealing relationships between sepal and petal measurements. Three Iris species—setosa, versicolor, and virginica—are distinguished by distinct geometric symbols (circle, cross, diamond) and colors. Built with D3.js v7, the SVG visualization uses `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.symbol` to render the points, axes, and a legend, updating the entire chart on each feature switch.
